This invention relates to hoist apparatus, and more particularly to a portable hoist outfit.

It has for its object to provide an improved portable hoist mechanism. A further object is to provide an improved hoist mechanism adapted to be run around a mine upon a track. A further object is to provide an improved portable outfit having a hoisting mechanism thereon and especially adapted to use as a scraper or loading mechanism. A still further object is toprovide improved driving means between said hoisting mechanism and the wheels upon which said outfit is mounted. Another object is to provide a truck having an electric cable reel and hoisting mechanism thereon, with improved means for .driving said truck from said hoisting mechanism. My improved device also contemplates the use of a hoisting mechanism, in combination with the previously mentioned driving mechanism for the truck, to assist in the moving of the truck, of a cable wound upon the drum means and anchored at some `distant point, such a construction thus permitting the truck to be moved up relatively stee gra-des upon which the truck Wheels wou d ordinarily slip. It is also an object of the invention to provide suitable means for anchoring the truck in position, and to provide improved means for disconnecting the driving connection between the truck Wheels and the hoisting mechanism, and to thereafter use the hoisting mechanism in combination with the iiexible member disposed thereon to operate a scraper such as in which my invention may assume in practice.`

In these drawings,- Fig. 1 is a side elevation of my improved outfit.

.ly adapted for scraper purposes as compris- .ing a rectangular shaped truck frame 1 having depending bearings-2 within Which are mounted rear and front axles 3 and 4 carrying wheels 5 adapted to run upon a track 6. Mounted uponthe rear end and opposite sides of the truck frame l are upwardly extending standards 7 which carry an electric cable reel 8 rotatably mounted therein as by a transverse shaft 9 and from which a cable 10 is adapted to be reeled out over idler pulleys 11 carried in a suitable supporting bracket 12 at the4 extreme rear end of said truck frame. Disposed upon the shaft 9 is a sprocket 13 which can be connected thereto as by any suitable friction clutch means not shown, which in turn is driven by a chain 14 passing around a sprocket 15 fixed to the rear axle 3 so'that upon movement of the truck in one direction the reel 8 will automatically unwind the cable 10 therefrom while upon movement in the opposite direction the same will be wound upon the reel. In this latter case the friction clutch between the sprocket 13 andshaft 9 will slip as the cable is wound upon the reel due to the increased diameter thereof but a continual driving action Will be imparted to said reel.

In` order to provide suitable driving means for the truck and to also assist in pulling the truck up a steep grade or to use the hoisting mechanism as a separate unit, I have pro-l.

vided on the front end of said truck a double drum hoist unit 16 which has a usual base 17' pivotally mounted upon the platform of the truck framel as by any desired construction as shown herein, a circular flanged plate 18 is fixed to the base and disposedwithin an opening 19, the same being held in any desiredV position as by pins 20 removablyl mounted in x any one of a series of holes formed in the ioor of the truck frame. The hoisting mechanism is of standard construction and briefly described com-prises a driving motor 21, herein shown as of an electric motor type but if desired could be of a Huid pressure actuated type, upon the periphery of which is mounted a drum 23 havlng a transverse member 24 and a stub shaft 25.l

' connected to the front axle 4 as by a chain 34 passing around a sprocket 35 fixed to said axle so that upon engagement of the clutch -32 and sprocket 33 the truck may -be driven through suitable operative connections between the electric motor 21 and the remaining drum structure.

The connections above referred to comprises a suitable gear train, generally indicated at 36, some of'which is mounted upon the transverse member 24 and adapted to mesh with an internal gear 37 mounted on an annular iange 38 removably secured to a radially flanged portion 39 carried by the shaft 27. The flange 38 carries usual brake bands 40 while an annular flange 41 formed on the` drum/also carries brake bands 42. Suitable means have been provided for transmitting electric current to the motor as from the cable 10, which means comprises a slip ring 46 car- Y ried on shaft 9 and adapted to be engaged by a suitable brush and plug structure 47 to which lead wires 48 are connected. These lead wires terminate in a controller box 49 so as to control either forward or reverse rotation of the electric motor, as by suitable mechanism controlled by a reverse lever 50. A cable 51 connects said control box and motor 21 and is of such length that upon swinging the hoist about its vertical pivot said connection will not have to be changed. Pivotally mounted upon the four corners of the truck frame are jacks 52 adapted to be thrown into engagement with the mine wall, roof, or other suitable stationary, support when it is desired to positively anchor the truck frame, while upon movement of the truck, said members may be placed upon outwardly extending arms 53 which serve as jack carriers.

In the operation of my device if it is desired to. drive the truck the brake b and 40 will be left free and brake band 42 tightened to hold the drum 23 in fixed position thereby causing rotation of the internal gear 37 as through the gear train 36, thus causing rotation of shaft 27 und sprocket 33 due to engagement of the clutch member 32. If it is desired to stop movement of the truck and slow the same down, the brake band41 is releasedand band 40 tightened. If it is desired to assist the movement of the truck the cable 43 mounted upon the other drum, which is identical in structure and operation as the drum 23, can be fixed to some stationary point disposed some distance ahead of the truck and upon operation of Isaid drum which' would be by the outer band 40, said cable will be wound in and thus help pull the truck along. It -is to be noted, however, that if a single drum type of hoist is desired to be used, the same additional pulling effect may be had. Even with the double drum hoist, should it be desired to use only one drum both for driving the truck wheels and for pulling the truck along, such is accomplished by simply connecting the cable wound u on the drum 23 to some stationary point in ront of the machine and then releasing both bands 40 and 41. The result is, an equalizing effect will be had between the sprocket 33 and the drum 23-to cause positive rotaticn of each so in case the Wheels in coming up a steep grade should have a tendency to slip, said cable 43 will tend to pull the truck along. This mode of operation will thereby leave one drum perfectlyfree to use as desired. If it is now desired to totally release the truck chain drive, the clutch 32 is pulled out and the hoist is then ready to be used as a scraping mechanism such for yinstance as passing the cable wound upon the separate drums to cause actuation of the Scrapers to load material into a mine car or other suitable receptacle. If necessary the hoist may obviously also be turned and locked in any lateral position to enable the material to be drawn `laterally toward the track. During all of these loading operations, it is usually found necessary to positively anchor the truck against movement and this is readily accomplished by the use of the jacks452 as before described. Y
